I want to ask about the steps to do this problem in excel.

8. Continue to assume that you can invest in the risk-free asset. Now calculate the efficient portfolio allocations required to achieve the 'floor' rate of return of 0.8% per month (mandated by the college) with the expanded universe of assets while also assuming that the college is not allowed to invest more than 40% in any asset class and that no short sales are allowed. What is the expected standard deviation of such a portfolio? 8. Continue to assume that you can invest in the risk-free asset.
